Satellite infestation – A location of balsam isolated from the wider infestation because of early invasion. You will find areas of land or h2o in proximity to your satellite infestation the place no balsam is current but still left uncontrolled the satellite is likely to become the resource in these spots read more by means of organic or manmade dispersal pathways.
No – While Himalayan balsam is really an invasive non-indigenous plant, it may be controlled by utilizing non-chemical strategies. It is often found growing on
In extremely damp soil, marginal plants would be suitable. Preferably, go with the ones that flower in late summer months and autumn to deliver pollinators with an alternate source of website nectar and pollen.
